Correlation Between Color and Pigment Components' Contents of Lycii Fructus Expressing Different Degree of Color-changing
Objective: To study the correlation between color of powder
extracting solution and pigment components' contents
such as carotenoids
rutin of Lycii Fructus expressing different degree of color-changing. Method: The colorimeter was used to determine the color of powder
fat-soluble pigments and water-soluble pigments extracting solution of Lycii Fructus. The ultraviolet-visible spectrophotometry was applied to determine carotenoid content. High performance liquid chromatography (HPLC) was applied to determine rutin content in Lycii Fructus. Result: With the appearance color deepening in Lycii Fructus
the colorimeter measured powders' brightness
reddish
yellowish extent showed a decreasing trend.The powder color was strongly correlated with water-soluble pigment extract solution color
and pigment components' contents. Conclusion: It was feasible to objectively and quantitatively measure external color of Lycii Fructus by colorimeter.The powder color was correlated with pigment components' contents
which showed that with color evaluating its inner quality is scientific.It laid the foundation for further development of rapid quality evaluation method of Lycii Fructus.
